| Description : |
Sonic hedgehog (SHH) is used to study differentiation and expansion of human and mouse embryonic and adult stem cells. Studies suggest SHH is involved in regulating stem cell fates of neural and hematopoetic lineages1. It controls cell division of adult stem cells and has been implicated in development of some cancers2. SHH is instrumental in early embryo patterning and development. It has been implicated as the key inductive signal in patterning of the ventral neural tube, the anterior-posterior limb axis, and the ventral somites3. The mature biologically active form of SHH molecule is produced by autocatalytic cleavage of its precursor protein and corresponds to approximately the N-terminal half of the precursor molecule. Sonic Hedgehog is an approximately 20 kDa protein expressed in E. coli consisting of 175 amino acid residues. |
